Anthropic Files for Up to $100 Billion IPO at $2 Trillion Valuation

Anthropic filed paperwork Monday for an initial public offering that could raise as much as $100 billion and value the company at up to $2 trillion, potentially making it the largest IPO ever and eclipsing SpaceX’s earlier $86 billion offering. The San Francisco company plans to list on the Nasdaq Global Select Market under the ticker symbol ANT, with a Wall Street debut expected next month.

The filing comes as other AI-related companies delay or suspend their stock market entries amid rising interest rates and market volatility. Data center operator Switch and AI infrastructure provider Nscale postponed their offerings, while SoftBank-backed SB Energy also delayed its listing. Blackstone-backed AirTrunk REIT and Nvidia-backed Firmus withdrew or suspended their offers.

“I do think there will be a bit of hype and frenzy around the name, given that it will be the first major generative AI pure play to come to market.”

Anthropic, founded in January 2021 by siblings Dario and Daniela Amodei after they served as OpenAI executives, reported a net loss of $80.7 billion in the first half of 2026, compared with a $13 billion loss in the same period a year earlier. The company behind the Claude chatbot has yet to turn a profit despite rapid revenue growth.

Private investors valued Anthropic at $965 billion earlier this year, but reports suggest the IPO valuation could reach $1.5 trillion or possibly $2 trillion. At $1.5 trillion, the five-year-old startup would rank among the world’s most valuable public companies alongside Tesla.

CEO Dario Amodei has argued for slowing development of the most advanced AI models, warning that advanced AI could pose an existential threat to humanity. An IPO would provide enormous resources to accelerate expansion and could boost the wealth of Amodei and his sister and co-founder by billions of dollars.

Reuters reported on Thursday that Anthropic might disclose its prospectus by the end of October and begin presenting shares to potential investors in the week of November 9, though people familiar with the matter cautioned the timeline could still change.
